Formation mechanism of starch nanocrystals from waxy rice starch and their separation using differential centrifugation

[Objective]In order to explore the formation mechanism of starch nanocrystals(SNC)during the whole hydrolysis process and proposed an interesting point on SNC separation by using differential centrifugation for collecting a suitable SNC product.[Method]Waxy rice starch was hydrolyzed by 3.16 M sulfuric acid solution preparing 15%wt suspension.The samples were collected at 1,2,3,5 and 7 days by successive centrifugations and were freeze-dried.The hydrolysis k…查看全部>>
